任何一种合金鋼也沒有像軸承鋼这样,在夹杂物含量、物理均勻性和組織致密性等方面要求更严了。这是由于金属存在夹杂物因而不够純淨,軸承表面不可能达到所要求的光洁度,就会在这些地方形成应力集中,造成軸承过早損坏。假若采用质量不高的鋼材制造,就不可能达到軸承轉动輕便的要求。若金属不够純淨和不够均勻,就不 Any kind of alloy steel is not as bearing steel so, the inclusion content, physical uniformity and tightness of the organization requirements more stringent. This is due to the presence of inclusions in the metal, which are not pure enough. It is not possible for the bearing surface to achieve the desired finish. Stress concentration can occur in these areas, causing premature bearing damage. If the use of low quality steel manufacturing, it is impossible to achieve lightweight bearing requirements. If the metal is not pure enough and not uniform, no
